The only difference is that in Russia the middle class, if there is one, lives in decay, and here mostly minorities do.
I love Moscow, if you still have any connections in Russia you should spend some time there for pleasure. There is a great series of books by DK publishing, www.dk.com which have beautiful maps and listings of out-of-the-way museums and attractions of various cities around the world.
I would mark on the map every night a route and we would start from one subway station and walk all the way through the city going from one place to the next. This was in January so it was usually snowing, but we saw most of the city. There is always a subway entrance close for when you are tired. Of course it is best if you know someone who speaks the language.
I find that all cities have their own distinct flavor, regardless of how rich or poor they are, and there definitely is a charm to Moscow. St. Petersburg is a must see also, which also has a book from DK.
Thanks for the tips.
